Hello Canon,

After a few hours of messing with my nephew's birthday present, a Canon MF665CDW, I came to make this easier to find.

[Power Save Mode]

[Menu]

[Preferences]

[Network]

[Wi-Fi Settings]

[Connection Set.]

When enabled, this mode will shut Wi-Fi connection off automatically to save power.
Terrible design default when the default connection is Wi-Fi - the user must first physically wake up the printer.
!!! Notice !!!

On the bottom of the Wi-Fi Settings menu, is the [Connection Set] button.

Greetings,

I have 2 Canon lasers running on two different networks. I made no changes to the power management settings on either device. Both sleep after 60 secs and both wake when a device connected to the same network sends/initiates a print job. No user intervention is required.

Based on your description, I suspect the issue is with your network configuration.

I'd like to make the following suggestions. 1. Assign or reserve a static IP for the printer on your router. 2. Install the printer as a TCP/IP device on your PC(s). This applies to Windows, MAC and to mobile devices if you're using the Canon print app. Relying on DHCP, Host name resolution or the ARP table on consumer networking equipment can be unreliable. If you have any questions, please let us know. 😉

Oh - I posted the solution
I disabled Power Save Mode

Now the printer is always connected to the WLAN.
